of these GZO/AZO thin films were investigated and compared with those of GZO and AZO thin films. The GZO/AZO (1:1) thin film deposited at 400 °C shows the electrical resistivity of 4.18×10-4 Ω?cm... decreases with increasing the Al ratio. Key words: multilayer; thin films; Ga-doped zinc oxide; Al-doped zinc oxide; pulsed laser deposition 1 Introduction Most of the research on the transparent......

of CFRP bars 加载后期,加固试件S-1d5-2和S-2d5-1的CFRP筋最大应变接近0.2,而加固试件S-1d7的CFRP最大应变为12.426×10-3,表明小直径CFRP筋可更充分发挥材料性能.此外,今后可进一步采用预应力CFRP筋增强板对石板进行加固,从而提高CFRP材料的有效利用率；同时,也可考虑采用其他种类的FRP材料,如GFRP等. 3 结论 1) 将预制CFRP筋...相同截面高度时2种石板加固方法的效果差异. 5) CFRP筋与增强板以及增强板与被加固石板之间的界面黏结性能整体良好,试验中未出现界面剥离和CFRP筋端部滑移破坏,试件工作性能良好. 6) 后续可考虑对增强板中的CFRP筋施加预应力,进一步改善被加固石板的抗开裂性能,提高CFRP筋材料的有效利用率. 参考文献: [1] 郭子雄, 黄群贤, 柴振岭, 等. 石结构房屋抗震防灾关键技术研究与展望[J......
